DETAILED DESCRIPTION

FIG. 1 is a perspective view of a stand alone air conditioning system 40with an air outlet structure 50 with progressively inclined partitionsin different directions in each row with the side walls of each rowprogressively inclined to each other.

FIG. 2 a is a perspective view of an air outlet structure with twolayers of adjustable air directors 100 a and 100 b perpendicular to eachother, the angle between each two directors is approximately constant asthey are pivoted to the main structures and connected by a rod to changethe direction the whole set.

FIG. 4 is a two-dimensional velocity vector-field close to apart-section 100 of a dispersing air outlet showing the turbulenceeffect caused by the partition walls 205, 206, 207 at the side wall 1.The arrows 14 present the imposing of the 3 dimensional air velocity asthe length of the arrows and the direction of the moving air at eachpoint. It is clear that the air flowing out of the air outlet 100 ishighly turbulent at all directions.

FIG. 5 shows the air outlet structure of FIG. 6 a and a diagram ofmeasured air velocities and air jet directions along the length of theentire air outlet structure.

FIG. 6 a is a longitudinal section, taken along line 1 a-1 a in FIG. 6b, of a dispersing air outlet structure showing air outlets emittingturbulent pulsating air streams from progressively endwardly inclinedair outlets.

FIG. 6 b is a cross section along line 1 b-1 b of FIG. 6 a with afogging nozzle 11 at the side of the dispersing air outlet structure.

FIGS. 6 a, 6 b and 5 show a preferred embodiment of an air outletstructure 100 according to the present invention. Turbulent pulsatingair streams are issued from air outlets 303, 302, 301 which are ofprogressively greater end ward inclination toward the left end of theoutlet structure and which each have an increasing cross section from anair inlet side extending outwardly. That is, air outlet 301 is moreleftward inclined than air outlet 302, which in turn is more leftwardinclined than air outlet 303, and the cross section of air outlet 301,for example, increases from the air inlet side, where the cross sectionis defined by the distance between points 501 and 502, to the air outletside, where the cross section is defined by the distance between points601 and 602. Air outlets 304, 305, 306 similarly have progressivelygreater end ward inclination toward the right end of the outletstructure 100, and each has an increasing cross section from an airinlet side extending outwardly. Due to the diverging direction ofadjacent air streams and to diffuser action, whorls are created betweeneach adjacent two air streams which effect substantially continuouschange in flow direction (e.g., turbulence) and flow velocity (e.g.,pulsation) as measured and recorded in FIG. 5. The turbulence of the airjets creates a mixing effect with the ambient air in front and sides ofthe air outlet structure.

FIGS. 6 a and 6 b show an outlet structure 100 which includes twoparallel longitudinal side walls 1 and several partitions 2 connectedbetween opposing side walls 1. A flange 3 surrounds an air inlet openingat the bottom of the structure. The flange 3 serves as a mounting flangeto couple the air inlet opening to an air duct or an outlet of an airconditioning system as will be described herein below. Any otherconnecting means can be used to couple the air inlet opening to an airduct or an outlet of an air conditioning system.

In the example shown in FIGS. 6 a and 6 b, seven partitions 201-207extend between the opposed longitudinal side walls 1. The partitions 2are progressively inclined toward the ends of the structure with respectto each other on both sides of a central upright prism shaped partitionas shown by progressively decreasing angles a, b, c, d. A central, prismshaped, partition wall 204 is substantially perpendicular to the twolongitudinal side walls 1 and partition walls 203, 202, 201 and 205,206, 207 are progressively endwardly inclined at respective angles b, c,and d as shown in FIG. 6 a. Angle a as shown in FIG. 6 a is preferablysmaller than 90 degrees. The angles b, c, and d at which the partitionwalls are progressively endwardly inclined may decrease by increments ofabout 10 degrees, or in a range of from about 1-20 degrees, 6-30degrees, and 15-45 degrees, respectively. For example, angles b, c, andd may be 80, 70 and 60 degrees, respectively. If an additional partitionwall is provided on each end of the air outlet structure, the angle ofinclination of such additional partition walls may decrease by a furtherincrement of about 10 degrees, or in a range from about 20-60 degrees.If still further partition walls are provided, the angle of inclinationof such further partition walls may decrease by further increments.

As shown in FIG. 6 a, a row of air outlets each having respective axes401-406 which are progressively endwardly inclined with respect to anadjacent air outlet is thus formed. End air outlets 307, 308 withrespective axes 407, 408 are also provided. The axis of each air outletis shown by a dotted line in FIG. 6 a, and angles e-h indicate theangles of inclination of the axes, as shown in FIG. 6 a. Specifically,the axis of a given air outlet (except the outermost air outlets 307,308) is defined as a plane running between the two longitudinal sidewalls defining the air outlet at an angle to the central partition wall204 that is about midway between the angle at which each of the adjacentpartition walls defining such air outlet is inclined with respect to thecentral partition wall 204. For example, the air outlet defined byadjacent partition walls 205 and 206 has an axis 405 defined by a planerunning between longitudinal side walls 1 at an angle f that is aboutmidway between the angles b and c at which partition walls 205 and 206are respectively inclined with respect to central partition wall 204. Itshould be noted that the respective outermost air outlets 307, 308 maybe open on their ends and may be defined by just one partition wall, 207and 201, respectively. In such case, the axis of each such outermost airoutlet 307, 308 is defined by a plane running between longitudinal sidewalls 1 and an angle a that is about somewhere between 1 degrees and theangle d at which the outermost partition wall, 207 or 201, is formedwith respect to the central partition wall 204.

As shown in FIG. 6 a, the cross section of each air outlet increasesextending outwardly from the air inlet opening on the air inlet sidetowards the open environment, as defined by the top of the outletstructure. For example, the cross section of air outlet 301 increasesfrom the air inlet side, where the cross section is defined by thedistance between points 501 and 502, to the air outlet side, where thecross section is defined by the distance between points 601 and 602.

Also as shown in FIG. 6 a, the partition walls 2 separating eachadjacent air outlet may also be spaced progressively closer togethertoward the respective outermost ends of the air outlet structure so thatthe cross section of successive adjacent air outlets decreases from thecentral portion of the air outlet structure to the respective outermostends thereof. (See, for example, the decreased cross sections ofoutermost air outlets 408 and 407.)

Instead of providing the air outlet structure with air outlets eachhaving respective axes which are progressively endwardly inclined withrespect to the adjacent air outlet as shown in FIGS. 6 a,6 b and 5, itis also possible to provide an air outlet structure having adjacent airoutlets whose axes are endwardly inclined in opposing directions and/orat increasing and decreasing angles of inclination. That is, adjacentair outlets on each side of the air outlet structure may have axes thatare endwardly inclined at increasing and decreasing angles ofinclination in the same end ward direction, and/or the air outletstructure may have adjacent air outlets whose axes are endwardlyinclined in alternating end ward directions. The critical feature isthat the air outlet structure issues turbulent pulsating air streams indiverging directions.

FIG. 7 is a top view of an air outlet structure including progressivelyinclined partitions and alternate outwardly inclined side wall portions.

FIG. 8 is a cross section of the air outlet structure shown in FIG. 7taken along line 8-8 in FIG. 7.

Still further, instead of providing the outlet structure with twoparallel longitudinal side walls 1 (as shown in FIGS. 6 a, 6 b and 5) itis also possible to form the side walls in a “zigzag” fashion, as shownin FIGS. 7 and 8, thereby also extending the air outlets sideways inalternate order. The air outlet structure 120 shown in FIGS. 7 and 8includes air outlets which, in addition to diverging from each otherendwardly along the structure (as in FIG. 6 a), extend sideward to theright and the left from a center line. The structure includes arectangular oblong inlet opening 5 surrounded by a flange 3,progressively endwardly inclined transverse partitions 102 and pairs oflongitudinal side wall portions 101 and 111 which are alternatelyinclined in opposite directions to the right and to the left from animaginary center line in FIG. 8. Since the center line extendshorizontally in FIG. 8, the pairs of longitudinal side wall portions101, 111 are alternately sideward inclined as seen in FIG. 8. In thisembodiment, the air outlets are thus both endwardly and sidewardinclined, causing the turbulence and pulsation of the emerging airstreams to further increase.

As shown in FIG. 8, the sideward angles of inclination of thelongitudinal sidewall portions 101 and longitudinal side wall portions111 comprising each pair of longitudinal side wall portions may differ.For example, the sideward angle of inclination of longitudinal side wallportion 101 may be about 70.degree, from the imaginary center line andthe sideward angle of inclination of longitudinal side wall portion 111may be about 80.degree, from the imaginary center line.
